CHICAGO, ILLINOIS, CORPORATION 0F RADIATOR.

Application 'led May 16,

. To all 'whom t 'may concern:

Beit lmown that we, Louis FABER and PHILIP SCHNi-iininz, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have jointly invented certain new and usefiil"Improve ments inRadiators, of which the following is a specification.

This invention relates to a new and improved radiator, and moreparticularly'to a. radiator of the type particularly adapted for'use inconnection with the cooling systems of internal combustion engines. Insuch radiators it is now customary to provide a' plurality of tortuouspassages so formed as to present a large area for contact with thev air.The efficiency of the radiator is limited by the area'of exposed coolving surface and is further' limited by the facility with which -air mayreach andpass over such ycooling surfaces.

In certain types fof radiator tively large varea of radiatorconstruction in order to aliord adequate cooling area. In radiators,especially those adapted oriise upon motor vehicles, compactness is anessential feature.`

It is an 4object of the present invention to provide a radiatorconstruction having a plurality of adjacent water pasages, thesepassages 'connected into a unitary structure `by separating means. theseparating means, however, affording air passages adjacent all parts ofthe surface of the water cooling members.

It is an additional object provme adevicc'of this character in whichtwo-separate air spaces are provided between eachuie fiattened waterpassages are formed with a number of 1921. Serial. N0. 489,774.

adjacent pair of water cooling members, one such space adjacent eachmember, the mein.A bers thus being kept out of contact with each other,and the spaces forminor continuous ai r passages bothI longitudinallyand transversely.

It is also an object to provide a structure in which this isaccomplished by means of a single s 'acing element placed between eachpair of a 'acent water cooling elements.

It is a urther object to provide a device of the character describedwhich is com pact and affords a maximum of radiation surface and whichis composed of but few and -relatively simple parts and which mag .bemanufactured at small cost.-

ther and further objects will appear as the description proceeds. j

Broadly, o ur invention comprises a series ofjuxtaposed water coolingmembers with a separator plate inter osed between each pair of suchmembers. are laterally dis laced in opposite direc tions, and theseispla'ced portions are attached to the two adjacent water. coolingmembers. v The major portion of the sepa rator plateis., however,unattached to either such water cooling member, and preferably airpassages extending both longitudinally and laterally of the surfacesofthe water cooling members are provided between each such member andits adjacent separator plates, I'

We have illustrated a preferred embodiment of Vc'iuiinvention intheaccompanying drawing, in which- Figure Ii is a -general view oftheradiator `structure according to our invention Y 'Y Figure- 2 is afragmentary view on an enlarged scale showing a portion of the coi1-struction Y Figure 3 is a vertical transverse sectioi: taken on line.3-3 of Fig. 5;

Figure 4 illustrates a series of elements used in forming the radiator;and v Figure 5 is a section taken on line 5 5 of Fi re2.- y s shown inthe drawings, the radiator is ortions of theplate formed of a pluralityof corrugated plates 6, these plates having their edges? laterally ioooffset from the main body of the plate. Between each air of such plates6 is located a separator p ate 8 having its edges 9 ollset in a mannergenerally similar to that ot' the plat`es 6. The offsets on the plate 6as shown are`o`f such a type that when the plates are juxtaposedhexagonal cells are formed.

As sliown'Din Figure 3, when the edges of the several lates are broughttogether there is formed 'etween the adjacent plates 6 a channel Wadapted to receive water. This channel has portions of alternatelygreater and less cross section due to the peculiar' configuration of theforming plates.

The spacing lates 8, as best shown in Figure 3, have t eir central orbody portion entirel flat, their edges only being deforme or laterallydisplaced so as to be engaged by anvil attached to the adjacent waterpassage formin plates. The offset of the edges of the p ate 6 is suchthat, as best shown in Figure 3, these lates, although joined at theedges to the ates 8, are else- Where separated from sucn lates formingair passages A 4which' are a so of varying cross section as are thewater passages. These air passages extend longitudinally of the radiatorplates-that is, vertically as shown in Figure 3. Transverse air passages13 through the radiator are falso formed between the lates.

The radiator may' e preferably manufac tured by plcingjagainst eachother a pluralitj7 of sections as shown in Figure 4, in which "a water"tissage forming plate 6 'is placed upon eac side' of a spacing plate 8.The laterally displaced edge portions 10 of V.the plate 8 arealternately brought into contact with the adjacent portions of each ofthe two water passage formig plates 6.

It will be observed that l.these portions 10 have a depressed portion'11 formed adjacent thereto. These depressions 11 are short and extend arelatively smallportion of the width of the plate, serving to receivethe ends of the de ressed portions 12 of the water passa e' ibrminglates, these latter depressions eing best -s iown in Figure 3. Thedepressions 12, however, extend suhstantially thev full width of theplates 6, their ends being. pocketed in the depressions 11 upon oppositeedges ofthe plate 8. The depressions 12 increase the areaiof the waterpassage and also by their seating in the' depressions 11' aid inmaintaining the plates 6 and 8 in their proper relation both .laterallyand longitudinally when handling the"pl'ates in forming thevradiators.

It will be observed that each element, as

shownin Figure 4, is provided with two vertically extending air`passages separated by the lplate 8. It is also provided with.transversely extending apertures 13..4 When two such elements areplaced together, the water passage W is formed lief/veen tl-zvrn,

In forming the radiator-a plurality of elements as show-n in Figure 4,of proper length, is placed in a form or jig and the edges of the platesare dipped in molten solder in order to fully close the ends andmaintain the plates in proper relation.

The completed radiator element then is placed in the radiator body 14 orhas its upper and lower faces connected in any desired manner toradiator body members to form a water tight connection therewith.

Obviously the effective thickness of the water passages may-be varied byvarying the amount of the offsets upon theedge of the plates; However',these offsets are limited by the nature of the material and the a cilitywith which it flows under formingV pressure.

The plates 6 and may be readily formedv by passing strips of the proper.width through forming rolls and may be easily bent and placed intoproper `Arelation, `as shown in the drawing.

The structure is very 'simple in design and inexpensive to manufacture,and is very eflicient in supplying both vertically and transverselyextending columns of air to-the water cooling passages throughout theexposed surface of the passages.

We claim:
